Wastewater-contaminated soil is noticed in many residential and industrial districts in various countries in the world. Domestic and industrial wastewater contains many injurious chemical compositions. Many underground septic tanks have been used to collect domestic wastewater from dwelling buildings in Tahta city, Egypt. Soil samples were taken at the depth of foundation level of the buildings and a series of mineralogical and chemical analysis was carried out for contaminated soil samples. Also, physical engineering properties of soil were identified and analyzed at different periods of wastewater exposure time and at variant distances from the contamination source (septic tank). Results showed significant adverse effects of the contaminated soil on mineralogical, chemical and physical properties.
